Takayasu arteritis with pulmonary artery involvement initially presenting as community-acquired pneumonia

Abstract

The initial clinical manifestations of pulmonary artery involvement in Takayasu arteritis were complicated and non-specific, making early diagnosis difficult. Three cases of Takayasu arteritis with pulmonary artery involvement (TA-PAI) initially presenting as community-acquired pneumonia (CAP) were reported. The clinical characteristics and lab test results of the three cases were summarized, and the relevant literature on TA-PAI mimicking CAP was concomitantly reviewed. It might be helpful in the early recognition and diagnosis of such patients.
